| Summary: | The management of advanced gastric cancer has improved over the past decade. There is more evidence to support the efficacy of systemic treatment in refractory gastric cancer beyond second-line treatment. Important randomized controlled trials of chemotherapies, targeted agents and immunotherapies have been reported. With the development of these novel therapies, clinicians can better individualize treatment for patients beyond progression on second-line therapy. However, there is no guideline on third-line therapy available for clinicians. This review discussed the efficacy and safety data from the pivotal trials of the agents proven to be effective in third-line settings, including the quality of study design, level of evidence and subgroup analysis, and how the data can help to guide clinicians on selecting the most appropriate third-line therapy for their patients.
